-
FIG. 1 schematically illustrates anexhaust system 10 according to the present disclosure.Exhaust system 10 can include at least anengine 12 in communication with afuel source 14 that, once consumed, will produce exhaust gases that are discharged into anexhaust passage 16 having an exhaust after-treatment system 18. Downstream fromengine 12 can be disposed a firstexhaust treatment component 20, which in the illustrated embodiment can include a diesel oxidation catalyst (DOC) 22. A secondexhaust treatment component 24 is coupled to firstexhaust treatment component 20 by acoupling system 26, as will be described in more detail below. Second exhaust treatment component can be a diesel particulate filer (DPF)component 28. - Although not required by the present disclosure, exhaust after-treatment system 18 can further include components such as a thermal enhancement device or
burner 30 to increase a temperature of the exhaust gases passing throughexhaust passage 16. Increasing the temperature of the exhaust gas is favorable to achieve light-off of the catalyst in theexhaust treatment component 20 in cold-weather conditions and upon start-up ofengine 12, as well as initiate regeneration ofDPF 28. - To further assist in reduction of the emissions produced by
engine 12, exhaust after-treatment system 18 can include adosing module 32 for periodically dosing an exhaust treatment fluid into the exhaust stream. As illustrated inFIG. 1 ,dosing module 32 can be located upstream of a thirdexhaust treatment component 34, and is operable to inject an exhaust treatment fluid into the exhaust stream. In the illustrated embodiment, thirdexhaust treatment component 34 is a selective catalytic reduction (SCR)component 36. In this regard,dosing module 32 is in fluid communication with areagent tank 38 and apump 40 by way ofinlet line 42 to dose an exhaust treatment fluid such as diesel fuel or urea into the exhaust passage 44 upstream of thirdexhaust treatment component 34.Dosing module 32 can also be in communication withreagent tank 38 viareturn line 46.Return line 46 allows for any exhaust treatment fluid not dosed into the exhaust stream to be returned toreagent tank 38. Flow of the exhaust treatment fluid throughinlet line 42,dosing module 32, andreturn line 46 also assists incooling dosing module 32 so thatdosing module 32 does not overheat. Although not illustrated in the drawings,dosing module 32 can be configured to include a cooling jacket that passes a coolant arounddosing module 32 to cool it. - The amount of exhaust treatment fluid required to effectively treat the exhaust stream may vary with load, engine speed, exhaust gas temperature, exhaust gas flow, engine fuel injection timing, desired NOx reduction, barometric pressure, relative humidity, EGR rate and engine coolant temperature. A NOx sensor or
meter 48 may be positioned downstream fromSCR 34. NOxsensor 48 is operable to output a signal indicative of the exhaust NOx content to an exhaust after-treatment system controller 50. All or some of the engine operating parameters may be supplied from anengine control unit 52 via the engine/vehicle databus to exhaust after-treatment system controller 50. The exhaust after-treatment system controller 50 could also be included as part of theengine control unit 52, without departing from the scope of the present disclosure. Exhaust gas temperature, exhaust gas flow and exhaust back pressure and other vehicle operating parameters may be measured by respective sensors, as indicated inFIG. 1 . - The amount of exhaust treatment fluid required to effectively treat the exhaust stream can also be dependent on the size of the
engine 12. In this regard, large-scale diesel engines used in locomotives, marine applications, and stationary applications can have exhaust flow rates that exceed the capacity of asingle dosing module 32. Accordingly, although only asingle dosing module 32 is illustrated for urea dosing, it should be understood thatmultiple dosing modules 32 for urea injection are contemplated by the present disclosure. - Now referring to
FIGS. 2-5 , firstexhaust treatment component 20 can include a cylindrically-shaped housing 54. At afirst end 56 ofhousing 54 can be attached anexhaust inlet 58.Exhaust inlet 58 can be conically-shaped, and can include atattachment ring 60 that can be bolted or fastened to an end ofexhaust passage 16.Exhaust inlet 58 can be secured tofirst end 56 ofhousing 54 by welding, by using a clamp (not shown), or by any other attachment method known to one skilled in the art. - Second
exhaust treatment component 24 can include a cylindrically-shaped canister 62. At asecond end 64 ofcanister 62 can be attached anexhaust outlet 66. Similar toexhaust inlet 58,exhaust outlet 66 can be conically-shaped, and can include atattachment ring 68 that can be bolted or fastened to an end of exhaust passage 44.Exhaust outlet 66 can be secured tosecond end 64 ofcanister 62 by welding, by using a clamp (not shown), or by any other attachment method known to one skilled in the art. - First
exhaust treatment component 20 houses asubstrate brick 70. Because firstexhaust treatment component 20houses DOC 22,substrate brick 70 can be catalyst-coated to achieve oxidation of the exhaust gases passing therethrough. Secondexhaust treatment component 24 also houses asubstrate brick 72. Because secondexhaust treatment component 24 housesDPF 28,substrate brick 72 can be a filter that is operable to filter soot and other particulate matter from the exhaust stream. Althoughexhaust treatment components DOC 22 andDPF 28, respectively, the present disclosure should not be limited thereto. In this regard,exhaust treatment components mat 74 can be disposed betweenbricks housing 54 andcanister 62, respectively.Mat 74 prevents heat inexhaust treatment component housing 54 andcanister 62 so that the catalysts ofDOC 22 andSCR 36 can remain at light-off temperature. -

In addition,first gasket flange 84 includes an axial component or circumferentially extendinglip 92 that receivessecond gasket flange 90 withgasket 86 therebetween.Axial component 92 ensures thatgasket 86 remains tightly secured between first andsecond gasket flanges gasket 86 between first andsecond gasket flanges gasket 86 includes agasket pilot ring 94 that extends axially relative togasket 86. During assembly ofexhaust treatment component 24 intoannular housing 54,gasket pilot ring 94 includinggasket 86 can first be seated againstfirst gasket flange 84, and then canister 62 includingsecond gasket flange 90 can be inserted to abut againstgasket 86 andfirst gasket flange 84. - At a location between
first end 88 andsecond end 64 ofcanister 62 can be disposed acleat ring 96.Cleat ring 96 can extend about an entire circumference ofcanister 62, and may be fixed tocanister 62 by welding, brazing, or any other attachment method known to one skilled in the art. As best shown inFIG. 4 ,cleat ring 96 extends radially outwardly relative tocanister 62, and includes a radius ofcurvature 98 in the axial direction. - To secure

At an end offemale component 102 opposite to threadedrecess 114,female component 102 can include a hemispherical-shapedbulb 116.Bulb 116 allowstension rod 82 to rotate away fromcanister 62 during insertion and removal ofcanister 62 fromhousing 54.Female component 102 is designed to feed throughaperture 80 offlange 78, withbulb 116 having a diameter that is greater than that ofaperture 80 that preventsfemale component 102 from feeding entirely throughaperture 80. - To secure first and second
exhaust treatment components system 26,gasket pilot ring 94 includinggasket 86 may first be seated againstfirst gasket flange 84. Then,canister 62 may be mated withhousing 54 such thatgasket 86 is positioned between first andsecond gasket flanges Female component 102 may then be fed throughaperture 80,retainer 108 may be disposed aboutmale component 100, andmale component 100 mated withfemale component 102. Asmale component 100 is mated withfemale component 102,retainer 108 should be oriented to mate withcleat ring 86. Asmale component 100 is further tightened, the mating betweencoupling 108 andcleat ring 96 will pullcanister 62 towardhousing 54 to further compressgasket 86, which results in a hermetic seal betweencanister 62 andhousing 54. - During tightening of
male component 100 relative tofemale component 102,bulb 116 may be inclined to rotate inaperture 80. To prevent rotation ofbulb 116 relative toaperture 80,bulb 116 may include ananti-rotation feature 118 that abutsflange 80.Anti-rotation feature 118 can be a notched portion formed inbulb 116. Outward fromanti-rotation feature 118, however,bulb 116 should be a curved hemispherical surface to allowtension rod 82 to rotate relative tocanister 62 during removal ofcanister 62 fromannular housing 54, as shown in phantom inFIG. 4 . - More particularly, during removal of
canister 62 fromhousing 54,coupling system 26 is designed to allow for rotation (arrow 120) oftension rod 82 relative to canister 62 that allows for easier removal ofcanister 62 fromhousing 54. In this regard, asmale component 100 is untightened fromfemale component 102, the mating force betweenretainer 108 andcleat ring 96 will be removed. Onceretainer 108 can be disengaged fromcleat ring 96,tension rod 82 andretainer 108 can be rotated away fromcanister 62 to allowcanister 62 to be gripped atcleat ring 96 and pulled outward fromhousing 54. - The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
